Sharing the journey of developing an ePortfolio assignment, this article focuses on the design process, implementation, and benefits of the ePortfolio as a capstone project for a bachelor's degree program using a constructivist approach. Integrating constructivist educational practices (e.g., student-centered learning, autonomy, self-regulation, mental relationships, and reflection) in the ePortfolio project design deepens student learning, offers a useful means for assessment of student learning through the degree program, and provides students with validation of their learning and development as professionals. Explaining the process of the implementation of the project in the capstone course, this article shows how students can co-construct knowledge in the context of a sociomoral atmosphere. The ePortfolio project serves as an instrument for student assessment and deepening of learning, and beyond graduation, it serves as a valuable tool for professional advancement.
